Appendix: Updating the

Connect

and

Presence

services using

Lync

Director

The

Lync

Director role provides functionality for users accessing the

Microsoft Lync Server

, internally and externally. For more information about the

Lync

Director, visit the Technet Wiki and see

Lync

Director.

To support this capability, the

Microsoft Lync Server

is deployed as one or more pools, based on Standard Edition or Enterprise Edition

Microsoft Lync Server

. Users can be homed on only a single pool. Clients can be configured to find their

Lync

pool automatically. However, the DNS records that support this functionality can point to only a single pool. In a multi-pool environment, this "primary" pool will have to redirect users to their correct home pool. This is an overhead on the primary pool. The

Lync

Director is used to offload this redirection functionality. The Director does not home any users itself but instead redirects the user to their correct pool home. The requirement for the Lync Director is therefore for multi-pool environments with high user numbers.

Once the user has been redirected to their correct pool, the

Lync

Director plays no further role in communications between the client and the pool server.
